Re: [opendds-main] (no subject) --> use_multicast option (3.5.1 VS 3.5.0)

[Hubert T. <Hub...@cr...>]

Hi,

My application works now.

Now, putting 'use_multicast=1", my application works well and after restarting a crashed publisher/subscriber, reconnection is done too.

After investigating the problem, I finally found that OpenDDS version (3.5.1) was not the issue.

In fact, I don't know yet what was wrong but after rebuilding all the modules, everything worked fine.

Maybe some kind of library mixing (at build time or at run time) was the problem...

Sorry for the inconvenience and thanks to all who work on OpenDDS.

Hubert

Hi,

Problem report form follows...

With OpenDDS-3.5.0, it was possible to use 'use_multicast' option set to 1 in a way that a crashed publisher/subscriber was able to reconnect with other publishers/subscribers when restarted.

It seems that something has changed in OpenDDS-3.5.1 with 'use_multicast' option (please, see report form).

What can I do to have the same behaviour of 3.5.0 of 'use_multicast=1' option ?

Thanks

Hubert

    SYNOPSIS:

        'use_multicast=1' produces a different behaviour from version 3.5.0
        to version 3.5.1 on my application.

    DESCRIPTION:

        Here is my rtps.ini file:

            [common]
            DCPSGlobalTransportConfig=$file
            DCPSDebugLevel=0

            [domain/11]
            DiscoveryConfig=fast_rtps

            [rtps_discovery/fast_rtps]
            SedpMulticast=1
            ResendPeriod=2

            [transport/the_rtps_transport]
            transport_type=rtps_udp
            use_multicast=1

        My application (multiple subscribers/publishers) has run well with
        OpenDDS-3.5.0. Now, with OpenDDS-3.5.1, my subscribers receive a bunch
        of topics every four seconds instead of receving each topic one at a
        time.

        When I set 'use_multicast' to 0, my application runs well.
        However, when a subscriber/publisher crashes and when 'use_multicast=0',
        reconnection is not done when restarting the crashed
        publisher/subscriber, what was possible with 'use_multicast=1'
        (OpenDDS-3.5.0).
